Is the 2012 BMW M3 Worth Buying?

The 2012 BMW M3 offers an intoxicating blend of high-performance driving and relative daily usability, but it's crucial to understand this is not a 'set it and forget it' vehicle. While immensely rewarding, potential owners must budget significantly for critical preventative maintenance to mitigate well-known, expensive failure points, particularly within the engine. Buy with an eyes-wide-open approach and a dedicated maintenance fund, and you'll own a legend; ignore its needs, and prepare for financial pain.
